Exodus 11:7

But among all the children of Israel shall not a dog snarl with his tongue, either at man or beast; that thou mayest know how wide a distinction the Lord will make between the Egyptians and Israel.

But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that the Lord doth put a difference between the Egyptians and Israel.

But against any of the children of Israel a dog won’t even bark or move its tongue, against man or animal, that you may know that Yahweh makes a distinction between the Egyptians and Israel.
